Error: repository has at least one unnamed head

When hg-cloning Octave, everything goes fine:

$ hg clone http://www.octave.org/hg/octave upstream
real URL is http://hg.savannah.gnu.org/hgweb/octave

so it seems the remote repo is intact. git-hg however fails with

I just ran into the same error today. I might dive into it later because we use hg at work and using hg itself is starting to drive me crazy. Even if I can't figure out how to patch the issue, I'll at least change the error reporting to use the commit hash instead of the revision number... (or try to, anyway)

Just ran into this same issue with the Hugin repository;

$ git hg clone http://hg.code.sf.net/p/hugin/hugin hugin-hugin
Error: repository has at least one unnamed head

However, I just discovered that git-hg actually supports fast-exports --force flag, so this works:

$ git hg clone --force http://hg.code.sf.net/p/hugin/hugin hugin-hugin
